A techno-economic analysis of mild catalytic pyrolysis (CP) of woody biomass followed by upgrading of the partially deoxygenated pyrolysis liquid is performed to assess this pathway’s economic feasibility for the production of hydrocarbon-based biofuels. The process achieves a fuel yield of 17.7 wt% and an energy conversion of 39%. Deoxygenation of the pyrolysis liquid requires 2.7 wt% hydrogen while saturation of aromatic rings in the pyrolysis liquid increases total hydrogen consumption to 6.4 wt%. Total project investment is $457 million with annual operating costs of $142 million for a 2000 metric ton per day facility. A ...

The goal of this paper is to evaluate the economic performance of co-located corn grain ethanol (Gen 1) and cellulosic ethanol (Gen 2) facilities. We present six scenarios to evaluate the impact of stover-to-grain mass (SGM) ratios on overall minimum ethanol selling price (MESP). For the Gen 1 plant, MESP is $3.18/ gasoline gallon equivalent (GGE) while for the Gen 2 plant it is $5.64/GGE. Co-located Gen 1 and Gen 2 plants operating at the lowest SGM ratio of 0.4 generates the lowest overall MESP of $3.73/GGE as well as the highest MESP for ...
